Disposing of the inverter
앫Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved
from Mitsubishi.
앫The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V,
W) is maintained.
앫Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected
motions.
앫When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
앫The key is valid only when the appropriate function setting has been made. Prepare an emergency stop switch separately to
make an emergency stop (power off, mechanical brake operation for emergency stop, etc).
앫Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.
앫The inverter can be started and stopped via the serial port communications link or the field bus. However, please note that depending
on the settings of the communications parameters it may not be possible to stop the system via these connections if there is an error
in the communications system or the data line. In configurations like this it is thus essential to install additional safety hardware that
makes it possible to stop the system in an emergency (e.g. controller inhibit via control signal, external motor contactor etc). Clear and
unambiguous warnings about this must be posted on site for the operating and service staff.
앫The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output may
damage the inverter as well as the equipment.
앫Do not modify the equipment.
앫Do not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the inverter.
앫The electronic thermal relay function does not guarantee protection of the motor from overheating.
앫Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.
앫Use a noise filter to reduce the effect of electromagnetic interference and follow the accepted EMC procedures for proper installation
of frequency inverters. Otherwise nearby electronic equipment may be affected.
앫Take appropriate measures regarding harmonics. Otherwise this can endanger compensation systems or overload generators.
앫When a 400V class motor is inverter-driven, please use an insulation-enhanced motor or measures taken to suppress surge voltages.
Surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.
앫When parameter clear or all clear is performed, set again the required parameters before starting operations. Each parameter returns
to the initial value.
앫The inverter can be easily set for high-speed operation. Before changing its setting, fully examine the performances of the motor and
machine.
앫The DC braking function of the frequency inverter is not designed to continuously hold a load. Use an electro-mechanical holding
brake on the motor for this purpose.
앫Before running an inverter which had been stored for a long period, always perform inspection and test operation.
앫For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity from
your body.
앫Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the
inverter fails.
앫When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter,
etc. Identify the cause of the trip, then remove the cause and power on the breaker.
앫When the protective function is activated (i. e. the frequency inverter switches off with an error message), take the corresponding
corrective action as described in the inverter manual, then reset the inverter, and resume operation.
앫Do not carry out a megger (insulation resistance) test on the control circuit of the inverter.
앫Treat as industrial waste.

3.3 Cables and wiring lenght
3.3.1 Cable size
Select the recommended cable size to ensure that a voltage drop will be 2% max.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque
to decrease especially at the output of a low frequency.
The following table indicates a selection example for the wiring length of 20m.
400V class (when input power supply is 440V)
The line voltage drop can be calculated by the following expression:
line voltage drop [V] =
Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque
reduction) in the low speed range.

WIRING
3.3.2 Maximum permissible motor wiring length
The maximum permissible length of the motor cables depends on the capacity of the inverter and the selected carrier
frequency.
The lengths in the following table are for unshielded cables. When shielded cables are used divide the values listed in the
table by 2. Note that the values are for the total wiring length – if you connect more than one motor in parallel you must
add the lengths of the individual motor cables.
Note that the motor windings in three-phase AC motors are subject to far more stress when operated via frequency
inverters than with mains operation. The motor must have been approved by the manufacturer for operation on a
frequency inverter.
In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially
for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the
inverter, consider the following measures:
앫Use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection
according to wiring length.
앫Limiting the voltage rise speed of the frequency inverter output voltage (dU/dT):
If the motor requires a rise speed of 500V/μs or less you must install a filter in the output of the inverter. Please contact
your Mitsubishi dealer for more details.
Setting of Pr. 72 PWM Frequency selection
(carrier frequency) 016 026 040 060 ≥ 095
1 (1kHz) or less 200m 200m 300m 500m 500m
2 to 15 (2kHz to 14.5kHz) 30m 100m 200m 300m 500m
≤ 50m 50m–100m ≥ 100m
Carrier frequency ≤ 14.5kHz ≤ 8kHz ≤ 2kHz
CAUTION
앫 Especially for long-distance wiring (particularly when employing shielded motor cables), the inverter may be affected by a charging
current caused by the stray capacitances of the wiring, leading to a malfunction of the overcurrent protective function or fast response
current limit function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side.
When the fast-response current limit function malfunctions, make the function invalid. When stall prevention function misoperates,
increase the stall level. (For Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention operation selection, refer to the Instruction
Manual.)
앫 For details of Pr. 72 PWM frequency selection, refer to the Instruction Manual.
앫 When using the automatic restart after instantaneous power failure function with wiring length exceeding 100m, select without
frequency search (Pr. 162 = "1, 11"). (Refer to the Instruction Manual).

3.4 Control circuit specification
3.4.1 Standard control circuit terminal layout
3.4.2 Wiring method
앫Strip off the sheath of the cable of the control circuit to wire.
Strip off the sheath about the size below. If the length of the sheath pealed is too long, a short circuit may occur among
neighboring wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it.
Use a bar terminal as necessary.
앫Loosen the terminal screw and insert the cable into the terminal.
앫Tighten the screw to the specified torque.
Undertightening can cause cable disconnection or malfunction. Overtightening can cause a short circuit or malfunction
due to damage to the screw or unit.
3.4.3 Wiring instructions
앫Terminals PC, 5, and SE are all common terminals (0V) for I/O signals and are isolated from each other. Avoid
connecting the terminal PC and 5 and the terminal SE and 5 (ground). Terminal PC is a common terminal for the contact
input terminals (STF, STR, RH, RM, RL, MRS, RES).
앫Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and
power circuits (including the 230V relay sequence circuit).
앫Use two or more parallel micro-signal contacts or twin
contacts to prevent a contact faults when using contact
inputs since the control circuit input signals are micro-
currents.
앫Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.
앫Always apply a voltage to the alarm output terminals (A, B, C) via a relay coil, lamp, etc.
앫It is recommended to use the cables of 0.3mm² to 0.75mm² gauge for connection to the control circuit terminals.
If the cable gauge used is 1.25mm² or more, the front cover may be lifted when there are many cables running or the
cables are run improperly, resulting in an operation panel contact fault.
앫The wiring length should be 30m maximum.
앫The level of the control signals can be switched over between positive (SOURCE) and negative (SINK) logic. The input
signals are set to source logic when shipped from the factory. To change the control logic, the jumper connector above
the control circuit terminal block must bemoved to the other position.

4 PRECAUTIONS FOR USE OF THE INVERTER
The FR-E700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may
shorten the product life or damage the product.
Before starting operation, always recheck the following items.
앫Use crimping terminals with insulation sleeve to wire the power supply and motor.
앫Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.
앫After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in
a control box etc., take care not to allow chips and other foreign matter to enter the inverter.
앫Use cables of the size to make a voltage drop 2% maximum.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor
torque to decrease especially at the output of a low frequency.
Refer to page 6 for the recommended cable size.
앫The overall wiring length should be 500m maximum.
Especially for long distance wiring, the fast-response current limit function may be reduced or the equipment connected
to the inverter output side may malfunction or become faulty under the influence of a charging current due to the stray
capacity of the wiring. Therefore, note the overall wiring length. (Refer to page 6)
앫Electromagnetic Compatibility
Operation of the frequency inverter can cause electromagnetic interference in the input and output that can be
propagated by cable (via the power input lines), by wireless radiation to nearby equipment (e.g. AM radios) or via data
and signal lines. Install an optional filter if present to reduce air propagated interference on the input side of the inverter.
Use AC or DC reactors to reduce line propagated noise (harmonics). Use shielded motor power lines to reduce output
noise.
앫Do not install a power factor correction capacitor, varistor or arrester on the inverter output side. This will cause the
inverter to trip or the capacitor, varistor, or arrester to be damaged. If any of the above devices is installed, immediately
remove it.
앫Before starting wiring or other work after the inverter is operated, wait for at least 10 minutes after the power supply has
been switched off, and check that there are no residual voltage using a tester or the like. The capacitor is charged with
high voltage for some time after power off and it is dangerous.
앫A short circuit or earth fault on the inverter output side may damage the inverter modules.
– Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by
peripheral circuit inadequacy or an earth fault caused by wiring inadequacy or reduced motor insulation resistance
may damage the inverter modules.
– Fully check the to-earth insulation and inter-phase insulation of the inverter output side before power-on.
Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc.
앫Do not use the inverter input side magnetic contactor to start/stop the inverter.
Always use the start signal (ON/OFF of STF and STR signals) to start/stop the inverter.
앫Across P/+ and PR terminals, connect only an external regenerative brake discharge resistor. Do not connect a
mechanical brake.
Also, never short between these terminals.

PRECAUTIONS FOR USE OF THE INVERTER
앫Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.
Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity may
damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected
incorrectly to short terminals 10-5.
앫Provide electrical and mechanical interlocks for MC1 and MC2
which are used for bypass operation.
When the wiring is incorrect or if there is a bypass circuit as shown
below, the inverter will be damaged by leakage current from the
power supply due to arcs generated at the time of switch-over or
chattering caused by a sequence error.
앫If the machine must not be restarted when power is restored after
a power failure, provide a magnetic contactor in the inverter's input side and also make up a sequence which will not
switch on the start signal.
If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the
power is restored.
앫Instructions for overload operation
When performing operation of frequent start/stop of the inverter, increase/decrease in the temperature of the transistor
element of the inverter may repeat due to a continuous flow of large current, shortening the life from thermal fatigue.
Since thermal fatigue is related to the amount of current, the life can be increased by reducing bound current, starting
current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and
the inverter may not start. Therefore, increase the inverter capacity to have enough allowance for current.
앫Make sure that the specifications and rating match the system requirements.
앫When the motor speed is unstable, due to change in the frequency setting signal caused by electromagnetic noises
from the inverter, take the following measures when applying the motor speed by the analog signal.
– Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them.
– Run signal cables as far away as possible from power cables (inverter I/O cables).
– Use shield cables as signal cables.
– Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

5 FAILSAFE OF THE SYSTEM WHICH USES THE
INVERTER
When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal may not be output at an
inverter fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures best
quality products, provide an interlock which uses inverter status output signals to prevent accidents such as
damage to machine when the inverter fails for some reason and at the same time consider the system configuration
where failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails.
Interlock method which uses the inverter status output signals
By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can be
detected.
Backup method outside the inverter
Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure
status of the inverter itself. For example, even if the interlock is provided using the inverter fault output signal, start
signal and RUN signal output, there is a case where a fault output signal is not output and RUN signal is kept output
even if an inverter fault occurs.
Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider
the backup system such as checking up as below according to the level of importance of the system. Check the
motor running and motor current while the start signal is input to the inverter by comparing the start signal to the
inverter and detected speed of the speed detector or detected current of the current detector. Note that the motor
current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if
the start signal turns off. For the logic check, configure a sequence considering the inverter deceleration time. In
addition, it is recommended to check the three-phase current when using the current detector.
Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed
command and detected speed of the speed detector.
